Bay City's sugar factory is actually in Monitor Township
Michigan Sugar's 1901 Bay City factory sits in Monitor Township and still processes local sugar beets after a century of company changes.
Michigan Sugar calls this its Bay City factory. The mailing address does too. The local map is more exact. The big plant on South Euclid Avenue sits in southeast Monitor Township. The township’s current master plan lists it as a main industrial area.
The factory opened in 1901 as the German-American Sugar Company. It was the fourth beet-sugar plant built around Bay City. The business later became Monitor Sugar Company. For much of the twentieth century, Monitor Sugar and Michigan Sugar were separate rivals.
That changed in 2004. Monitor’s beet growers and Michigan Sugar joined forces to buy the factory, folding it into the grower-owned cooperative. The plant kept running, and the older Monitor name became part of the company’s history rather than the sign over the gate.
The scale is still easy to underestimate. Michigan Sugar says the factory processes about 1.65 million tons of beets in a year. It also produces roughly 480 million pounds of beet sugar. A product sold across the region under the Pioneer name still begins with farm trucks arriving in Monitor Township.
